Just listen to your speakers and enjoy them. They will break in gradually over time and you'll probably not notice much, since you'll get use to them. Just avoid really loud volume at first; and just use lower volume when you leave the system on while not listening.
Not sure "pink noise" would do the trick. Woofer/Mid drivers will break in some my moving. Most tend to be a little on the stiff side when new. A constant tone or noise may not do this.
Rock or Jazz probably does not really matter either. I would not break in speakers at high volume anyway. At lower volume they are likely to have about the same effect.
Play some jazz/rock... LOL !!
